Abstract: 1296396 Welding by fusion FOSTER WHEELER JOHN BROWN BOILERS Ltd 24 Feb 1970 [26 Feb 1969] 10405/69 Heading B3R In TIG welding, particularly internal end-toend tube welding, the parts to be welded are separated by a small gap and probe means for detecting the position of the gap comprises a jet of inert gas issuing from the torch, the torch being moved relatively to said parts whilst flow rate or, as particularly described, back pressure of the jet, reflecting misalignment of the jet with the gap, is measured, until jet/gap alignment is achieved. The torch may be such that on jet/gap alignment the electrode is aligned in readiness for welding, or such that on jet/gap alignment it is necessary to move the torch a known amount for electrode alignment. As shown, the tubes 12, 14 are spaced at 20 by a consumable filler ring insert 18 in weld preparations 16. The torch has a rotatable stem 10 comprising an outer ceramic tube 22 and nested tubes 30, 32 therewithin. A tungsten electrode 24 is screw-secured in a copper block 26 on the end of the tube 30 and projects through a hole 23 in the outer tube 22. The inner tube 32 directs electrode cooling water. Inert shielding gas (e.g. argon) is directed between the tubes 22, 30 and through the hole 23. The same inert gas is fed through a tube 34 and a nozzle 38 extending through a hole 39 in the tube to provide the probe jet. The jet back pressure is determined by the amount of its impingement on the walls of the tubes, jet alignment being indicated by a marked drop in back pressure.

Abstract: 1297106 Ink-drop writers A B DICK CO 20 Jan 1970 [21 Jan 1969] 2793/70 Heading G4H In an ink drop writing system where a stream of ink drops charged by video signals are projected at moving printing paper from a carriage moving back and forth across the paper, the charging of the ink drops is delayed momentarily after the carriage has started upon a fresh line of print to allow the carriage to reach a constant speed so assuring that each line of print begins at the same distance from the edge of the paper. Print data in 8-bit binary form from a source 84, such as a magnetic core or tape store, a keyboard or transmission line, enters 8-bit register 86 bit by bit under control of a clock 87, except during periods of carriage return, determined by beginning and end of line photosensors 90, 88. Satisfactory identification of a beginning of line character by gates 89 starts the carriage moving and resets count of 8 counter 92, every eighth clock pulse causing a single character to enter register 94. The carriage on reaching a predetermined position on the page where its speed is expected to be constant generates a photo-electric signal by sensor 100 which enables synchronizer circuit 98 to generate a transfer signal to transfer the character in register 94 to a circuit 96 to convert it into a video signal which is passed to a circuit 102 where it is converted into a form able to charge the ink drops. The generation of the transfer signal by circuit 98 is delayed for 10 Ásecs. if a clock pulse from counter 92 is received simultaneously with the photoelectric carriage signal from 100 to enable the buffer register 94 to fill.

Abstract: 1303254 Automatic level control ASHMORE BENSON PEASE & CO Ltd 25 Sept 1970 [3 Oct 1969] 48804/69 Heading G3R A blast furnace is supplied with materials continuously at a variable rate which is controlled by signals representative of the level of material in the furnace or of the rate of movement of the upper surface. As described, coke, sinter, limestone and dolomite are supplied via weighing hoppers and duplicated conveyor belts to a common conveyor belt supplying the mixture to the top of the blast furnace. A probe is maintained in contact with the top of the material in the furnace by supporting it on a line which is taken in or payed out by a winch as necessary to maintain constant tension in the line automatically. Rotation of the winch is thus an indication of the level in the furnace and the winch operates, through gearing and selsyn transmission systems, a level recorder and a level indicator having coarse and fine dials. In addition, the winch operates a generator 56B, Fig.3, pulses from which are counted over successive periods determined by a low frequency pulse generator 64 and stored at 63. These counts, which correspond to rate of change of level, are converted to analogue form at 71 and compared with a desired rate of change at 72 so that any error controls at 73 the speed of the conveyors, which may alternatively be skip hoists pneumatically or electrically controlled, to obtain the desired rate of change of level. If the rate of change of level gets outside predetermined limits controller 72 sets the conveyor speed to maximum or zero as appropriate. Limit switches operated by the winch control the conveyors in a similar manner if the level gets outside predetermined limits. The mean of signals derived from a plurality of probes detecting change of level at different positions may be utilized for control. The winch may alternatively operate a potentiometer or coded light disc to detect change of level. In an analogue arrangement, a tachometer generator driven by the winch may replace pulse generator 56B. Change in the level may alternatively be detected by its effect of radiation, capacity or ultransonic signals at a number of different positions vertically spaced. A modification in which rate of charging is varied in correspondence with actual level is referred to.

Abstract: 1310012 Crane safe-load indicators B & A ENG CO Ltd 19 March 1970 [5 Feb 1969 12 Dec 1969] 6313/69 and 60842/69 Heading B8B A crane safety device gives warning of incipient tipping and incorporates supplementary safety features, giving warning, for example, of approach to the limit of the structural strength of the jib and of bending of the jib under load increasing the danger of tipping. As shown in the drawing accompanying provisional Specification 1,310,012 hydraulic actuators 6, 7 connected to the top and bottom of a luffing ram (not shown) act on a lever 8 pivoted at 9 and transmit a force representative of the load through a plunger 10 to a lever 11 pivoted at 12. A cam lever 17 is acted upon by a cam 18 rotated through lever 20 in response to the jib angle and moves a fulcrum 16 between the lever 11 and an operating lever 14 pivoted at 15 and having its rotation resisted by a spring strut 21. Certain preselected moments applied to the lever 14 result in switches 22a and 22b being closed in turn to give warning when the rated load is approached and exceeded. A rod 23 is attached to a spring 24 secured to a cam roller lever 26 pivoted at 27 and following the contour of a cam 29 rotated in response to either the crane operating radius or to the jib extension, through a lever 31. The other end of the rod 23 is attached to the lever 14 and thus provides a supplementary force acting thereon. The device shown in the drawing accompanying the complete Specification 1,310,012 provides a supplementary force to a crane safety device operating lever (such as 14 above) through a rod 20. A first lever 5 pivoted at 6 is loaded by a spring 7 against a first cam 3 rotated in response to jib extension. The spring 7 also acts on a first member 8 of a compound lever arrangement to pivot it about a pivot 9 and transmit a force through movable fulcrum 10 to the other member 18 of the compound lever arrangement. The position of the movable fulcrum 10 is determined by a second cam 16 rotated in response to the crane operating radius to rotate a lever 13 about a pivot 14 and thus adjust the position of a rod 12 attached to the movable fulcrum 10. The supplementary force transmitted by the rod 20 thus depends on both the jib extension and on the crane operating radius. In the full line position shown the supplementary force is zero and corresponds to minimum jib extension. The dotted line position corresponds to maximum jib extension and minimum operating radius.
